Capacitive touch drive IC: FT6236G
The driving timing of this display screen is 3-wire 9BIT . If the main control does not support it, GPIO can only be used to simulate
Note: The display driver is not a standard protocol, and there is no DC for 3-wire 9bit. The first bit is used as the DC.
Many microcontrollers do not support hardware in this mode, so they can only use GPIO to simulate timing,
The speed will be relatively slow. Mind if you consider paying carefully.
interface
